To all whom t may concern Be it known` that I, l/VILLIAM M.

. Hart, a citizen of the United States, residing or extension in a single piece, and forming at the city of St. Louis, State ofv Missourtfl haveinvented a certain new and useful 1111-; provement in Locomotive-Frames, of which ther following is a full, clear, and eXact description, such as will enable others skilled inithe art to which it appertains to `n'iakefand usefthe same, reference being had to the accompanying -dr wings, forming part of this specification, in which- Figure1 is a top plan view of a locomotive frame of' my improved construction.

Fig. -2 is a side'elevation'al viewv ofthe frame. Fig; 8 is a section taken approxi-v matelyl on the line 3 3. of Fig. 1. Fig. t

is a transverse section taken approximately on theline t-4 of Fig. 1. Fig. 5 is a transverse section taken approximately'on the' line 5-5 of Fig. 1.

My invention relates generally to locomo- C tive frames and more particularly to a one piece rear extenslon for the main frame of` afterfbeing properly "assembled, 'are con-v nected to the m'aln frame by' machine-fit bolts. Such construction has many disadvantages for the reason that the strains and constant vibration developed vwhen the frame is in service tends to loosen the joints between the' assembled parts, thereby destroying the stability of the frame and the alinement and position of the various bear-A lngs and brackets whlch recelve certam de` vices particularly associated'with and carriedby the rear frame or extension. Furthermore, making the j frame' inseveral pieces, necessltates-a considerable amount .of machine work and other finishing; likewise the setting of a large number of rivets vand bolts. Y

It is the principal object of my invention to overcome the objectionable features just mentioned by casting the` rearA frame integral therewiththe necessary brackets and bearings, thus producing a very strong, rigidand substantial structure which, in

service, eifectually resists all` strains to 'my invention consists-inl certain novel feaparts, hereinafter is not affectedv bythe constant vibration de veloped in service. With the-above and other objects in view,

tures of construction and` arrangementv of more fully described ,and claimed.

' which it is ordinarily subjected, and which il. SHEE- .As shown in the accompanying drawings,

my :improved rear frame or .extensionV includes a .pairof parallel side members l0,

f which may beof any desired cross sectional shape, lsuch as for instance, channels having outwardly presentedvianges. The forward ends of the webs of these side membersv are devoid of flanges, and their outer'faces 'are preferably machined' and provided ,with` bolt holesv in order to be properly connected to the side frames A of the mainframe of the locomotive. The `tor-'ward ends of the members 10 .are united by transversely disposed integral webs or plates 11,` and formed integral ywith the inner edges of these plates is a transversely disposedl vertical wallor plate 12 which serves as a support and point of' connection for the frontend of theflre box.

Formed integral with the forward portions of the members 10 `are outwardly projecting brackets 13, in the outer portions of which are formed apertures 15 adaptedto receive brake hanger pins. Formed integral with the lower portions of the members 10 and neartheir front ends are' outwardly projecting horizontally' disposed plates 16 which serve as supports for equalizer fulcrums. connectingtheforward portions of the members 10 and a short distance't the rear of wall 12 is an inclined plate 17,'whic'h, in addition to .forming a cross tie, serves asia portion of the frontwall of the front 'ash pan B, the'upper edge of the front wall of the ash pan proper being-,attached in any suitable manner to the llower edge of thisl transverse wall. (See dotted lines, Fig. 2.)

Foinied integral with and Formed integral with and arranged be'- tween the central portions of themembers 10 is a plate 18 which is arched or substantially of inverted U-shape in cross section, and said arched plate in addition to formin'g a tie between the central portions of the members 10 serves as portions of the walls of both front and rear ash pans.,

The upper edge of the rearwall o'f the as a support and point of attachment for the ash pan B is attached to the lower front edge of the arched plate 18 and the rear, Wall of the 'front ash pan C is attached toI the lower front edge of said arched plate.` The upper edges of the side walls of pans A. t .and B are attached in any suitable manner, l

i ward above the top plate 27, to form a transto the lower flanges of side members 10;

Formed integral With and projecting outwardly from the members 10 and, at points between the plates 17 and v18 are pairs ofiA brackets 19, the same being transversely perjforated in order to'receive the pins whichE are utilized for attaching the spring yokes D to the frame. Formed integral .with the members 10 to the rear of the arched plate 18 are outwardly projecting horizontally disposed plates or brackets 20 and formed integral with -the forward outer corners thereof are pairs of lugs 21-'which are transversely perforated in order to 'receive pms utilized for attaching the lower ends ofv spring hangers E. Formedintegral with .the undersides of the plates 20 and inv lon-A gitudinal alinement with the brackets 19 are brackets 22 which are perforated in order to receive the rear pair of spring yoke at;

- y be saved. Furthermore, the elimination of taching pins.

j A transversely disposedinclined plate 23 is arranged between the members'lO to the rear of plate 18, thus forming a portion of? the rear Wall of the rear ash pan C, and the upper edge ofthe rear wall of the body of1 this' ash panis-connected in any suitable` manner to the lower edge of said inclined plate. In my improved frame those por` tions of the members 10 betweenlthe `transl verse members 17, 18, and 23 form side walls for `the upper portions of the ash pans.

. Formed lintegral with the members 10 to the rear of the inclined wall 23 is a transverse wall 'or plate 24, the lower portion of which is provided with a forwardly projecting flange 25 and this wall and flange serve central portion of the rear of the lire box.

` Formed integral with the rear portions ofA the plates 20`are upwardly projecting transversely disposed ribs or flanges 26, which are substantially in transverse alinement with the wall 24, and theseribs or flanges serve as supports and points of attachment for the outer portions of the rear end of the fire box. The rear portions of the members 10 are united by an integral structure comprising a horizontally disposed top plate 27, bottom plate 28, intermediate plate 29,-and'rear end plate 30. The bottom plate 28 is lpreferably located in a plane a short distance below the undersides of the members 10, andarranged between said'bottomp'late Aand intermediate plate 29 are'longitudinally disposed Webs or walls 31. The-space between these walls and the bottom and intermediate plates is occupied-by the rear draw bar, the'same being connected to the frame by means of a .the scope of which is set suitable. pin which passes throingzgh,openingsl 32 which are formed in .the bottom Land intermediate .plates. Formed 'integral` with Athe end plate '30 is a housing 33, open at its outer/end and which serves as a bulier pocket.' The rear plateV 30 is extended upversely disposed, rib or flange 34 which serves as av seat'and point of attachment for the cab bracket Formed vintegral with the rear ends of t-he members 10 are depending lugs or brackets 35 which are transversely perforated in order to receive attaching pins for the safety chain clevises.

The-rear portion 28a of the bottom plate 28 serves as a seat-and point of attachment for the truck centering device.

A rear extension for locomotive frames of `my improved -construction is very strong, can be readily produced inasmuch as it can be easily cast in a single piece, and by forming integral with said frame a number of essential brackets, bearings and the like much time, labor and consequent expense incident to the attaching of separate parts can joints in the frame does away'with structural weaknesses which invariably develop when anassembled or fabricated structure is subjected to service strains and vibrations.

A one piece .casting can be produced in soA much less'time' and withl less labor than a l sion frame can `be* made and substituted for those herein shown and' described, without departing from `the spirit of my invention,

forth in the'appended claims.
